Engine data from climate control system
If you press and hold the REST button for about 10 seconds you can access a menu of live engine engine data.
For example, Number 21 is a digital RPM readout. There's coolant temp, etc as well. 100 params in all.
Does anyone have a list of what these are? I'm especially interested in finding boost. I found one that is "13,0 bar" at idle. Anyone suggest how to interpret that?
Thanks,
Dave

Here's a partial list I found, but its climate-control specific:
1 - in-car temp. sensor reading;
2 - outside air temp. reading;
3 - left heater core temperature sensor;
4 - right heater core temp. sensor;
5 - evaporator temp. sensor;
6 - engine coolant temp. sensor;
7 - refrigerant pressure (in bar) – to convert to psi multiply by 14.7;
8 - refrigerant temperature at receiver/dryer;
10 - blower regulator control voltage (1 to 6 volts);
11 - emission sensor voltage (2.1 volts is about normal);
12 - sun sensor voltage (drops as light increases);
22 - vehicle speed (mph);
24 - battery voltage
